DETAILED DESCRIPTION

Various embodiments are directed to improving image processing byidentifying which colorspace model is most appropriate to use fordetection in a particular environment, e.g., to convert betweencolorspace(s) to improve detection within particular environments or inassociation with particular targets. In various embodiments, theconversion between colorspace(s) provides for a matrix located on anobject or displayed by an electronic device, where the matrix isoptimized for detection in an environment by performing one or morecolorspace conversations in generating the matrix. In one or moreembodiments, the matrix is a matrix barcode, and in one or moreembodiments, the matrix barcode is a fiducial marker.

In various embodiments, the colorspace conversion encodes informationwith respect to a matrix barcode, which permits proper scanning of theobject associated with the matrix barcode, while preventing tamperingand false verifications, e.g., the color-channels containing theinformation are tied to the conversion, and without having a scanningdevice accessing information related to the conversion, the scan cannotverify the object associated with the object and/or access anyinformation associated therewith.

In various embodiments, a colorspace conversion provides for increasingthe amount of information stored on the matrix, e.g., matrix barcode, asthe color-channels associated with the converted-to (derivative)colorspace can be increased as needed, without any limitation (providedthe scanning equipment is suitably configured to make detections whenthe matrix is scanned).

In various embodiments, to further increase the information associatedwith the matrix, add additional layers of security, and/or make optimaluse of inks associated with printing the matrix, ultraviolet and/orinfrared layers can be used with respect to the matrix.

Accordingly, various embodiments of the present disclosure provide atleast one of the following advantages: i) enhancing detection of animage, e.g., matrix, on an object in an environment, (as the matrixcolors are selected and optimized with the colors of the environment inmind), ii) providing for a more secure verification, and iii) storingmore information on the matrix, as there are no front-loaded limitationson how many color-channels can be employed, and the amount ofinformation can be further increased, and a verification scan made moresecure, by adding infrared or ultraviolet features.

In various embodiments, the colorspace conversions improve edgedetection. In image processing, edge detection is a known technicalfield and techniques for edge detection provide different results fordifferent colorspace models. It is not unusual for one colorspace modelto provide better results over another colorspace in edge detectionbecause having image data in accordance with the colorspace model has ahigher likelihood of success in edge detection than the other colorspacemodel.

Colorspace models are configured to represent color data, but mostmodels differ in their representation of that color data. For instance,the CIELAB or LAB colorspace model represents color as three values: Lfor the Luminance/Lightness and Alpha (A) and Beta (B) for the green-redand blue-yellow color components, respectively. The LAB colorspace modelis typically used when converting from a Red-Green-Blue (RGB) colorspacemodel into Cyan-Magenta-Yellow-Black (CMYK). For some images,representing its color data in the LAB colorspace model provides betteredge detection results than other colorspace models including the RGBmodel. As a result, the embodiments can improve affordability,scalability, modularity, extendibility, or interoperability for anoperator, device or network that utilizes image detection as a means ofverifying a transaction by providing a more effective and accuratemanner of scanning an image associated with the verification (and byextension, minimizing redundant consumption of computer resources).

With general reference to notations and nomenclature used herein, thedetailed descriptions which follow may be presented in terms of programprocedures executed on a computer or network of computers. Theseprocedural descriptions and representations are used by those skilled inthe art to most effectively convey the substance of their work to othersskilled in the art.

A procedure is here, and generally, conceived to be a self-consistentsequence of operations leading to a desired result. These operations arethose requiring physical manipulations of physical quantities. Usually,though not necessarily, these quantities take the form of electrical,magnetic or optical signals capable of being stored, transferred,combined, compared, and otherwise manipulated. It proves convenient attimes, principally for reasons of common usage, to refer to thesesignals as bits, values, elements, symbols, characters, terms, numbers,or the like. It should be noted, however, that all of these and similarterms are to be associated with the appropriate physical quantities andare merely convenient labels applied to those quantities.

Further, the manipulations performed are often referred to in terms,such as adding or comparing, which are commonly associated with mentaloperations performed by a human operator. No such capability of a humanoperator is necessary, or desirable in most cases, in any of theoperations described herein which form part of one or more embodiments.Rather, the operations are machine operations. Useful machines forperforming operations of various embodiments include general purposedigital computers or similar devices.

Various embodiments also relate to apparatus or systems for performingthese operations. This apparatus may be specially constructed for therequired purpose or it may comprise a general purpose computer asselectively activated or reconfigured by a computer program stored inthe computer. The procedures presented herein are not inherently relatedto a particular computer or other apparatus. Various general purposemachines may be used with programs written in accordance with theteachings herein, or it may prove convenient to construct morespecialized apparatus to perform the required method steps. The requiredstructure for a variety of these machines may appear from thedescription given.

Reference is now made to the drawings, wherein like reference numeralsare used to refer to like elements throughout. In the followingdescription, for purposes of explanation, numerous specific details areset forth in order to provide a thorough understanding thereof. It maybe evident, however, that the novel embodiments can be practiced withoutthese specific details. In other instances, well-known structures anddevices are shown in block diagram form to facilitate a descriptionthereof. The intention is to cover all modifications, equivalents, andalternatives consistent with the claimed subject matter.

FIG. 1 illustrates a block diagram for a system 100. Although the system100 shown in FIG. 1 has a limited number of elements in a certaintopology; it may be appreciated that the system 100 may include more orfewer elements in alternate topologies as desired for a givenimplementation. The system 100 may implement some or all of thestructure and/or operations for the system 100 in a single computingentity, such as entirely within a single device.

The system 100 may comprise an apparatus 120. The apparatus 120 may begenerally arranged to process input 110 using various components andgenerate output 130 of which (some) output 130 is displayed on a displaydevice or printed on a suitable material surface. The apparatus 120 maycomprise a processor 140 (e.g., processing circuit) and computer memory150. The processing circuit 140 may be any type of logic circuit and thecomputer memory 150 may be a configuration of one or more memory units.

The apparatus 120 further includes logic 160 stored in the computermemory 150 and executed on the processing circuit 140. The logic 160 isoperative to cause the processing circuit 140 to process image data ofimage datasets 170 into patched image data where the image data is beingconfigured in accordance with a colorspace model. The colorspace modelas described herein refers to any suitable colorspace model, such asRed-Green-Blue (RGB), Cyan-Magenta-Yellow-Black (CMYK),Luminance-Alpha-Beta (LAB), and/or the like. For example, the Alpha andBeta channels of the LAB colorspace model refer to green-red andblue-yellow color components, respectively. The green-red component mayrepresent a variance between red and green with green in the negativedirection, and red in the positive direction along an axis and theblue-yellow component may represent a variance between blue and yellowwith blue in the negative direction and yellow in the positive directionalong an axis. In various embodiments, an edge may be defined(mathematically) as each pixel location where the Alpha channel has avalue of zero (0) or near zero.

In various embodiments, the patched image data includes a plurality ofpatches of which each patch comprises color data (e.g., pixel data whereeach pixel is represented as a tuple of Red-Green-Blue (RGB) colorintensities). As described herein, one colorspace model (e.g., RGB) maycorrespond to a higher likelihood of success in edge detection thananother colorspace model. Some images provide optimal or near-optimaledge detection results when arranged in RGB while other images provideoptimal or near-optimal edge detection results when arranged in LAB oran XYZ colorspace and vice versa.

In various embodiments, the logic 160 is further operative to cause theprocessing circuit 140 to apply the colorspace transform mechanism 180to the image data to generate the transformed image data in accordancewith the other colorspace model. Then, the logic 160 is operative tocause the processing circuit 140 to apply an edge detection technique190 to the transformed image data. The edge detection technique 190 isan image processing technique that refers to any one of a number ofalgorithms for identifying edges or boundaries of objects within images.In general, the edge detection technique 190 provides information (e.g.,pixel data) indicating positions of edges in the image data of the imagedatasets 170. Some implementations of the edge detection technique 190operate by detecting discontinuities in brightness and, for thoseimplementations, having the image data in a LAB colorspace, or XYZcolorspace over RGB provides more precise edge detection results. Someimplementations of the edge detection technique 190 provide accurateedge detection results when the image data is modeled according to HCL(Hue-Chroma-Luminance) instead of RGB.

In various embodiments, the logic 160 is further operative to cause theprocessing circuit 140 to identify an image group corresponding to thepatched image data. The image datasets 170 further includes image groupmodel data correlating images with a colorspace model most likely toprovide appropriate edge detection results. In various embodiments, theimage group model data indicates which colorspace model to use intransforming a given image prior to edge detection to achievenear-optimal edge detection results. The logic 160 is further configuredto cause the processing circuit 140 to select a colorspace transformmechanism 180 based upon the image group. The colorspace transformmechanism 180 is operative to transform the image data into transformedimage data in accordance with another colorspace model, the othercolorspace model having a higher likelihood than the colorspace model atedge detection for the image group. It is appreciated that the othercolorspace model may be any colorspace model including those with adifferent number of channels than the colorspace model.

In various embodiments, the logic 160 can be further operative to causethe processing circuit 140 to determine a colorspace that is optimal fordetection in association with a particular object, entity, orenvironment, where a colorspace or histogram representation of theparticular object, entity or environment can be part of the imagedatasets 170. The logic 160 can be further operative to cause theprocessing circuit 140 to determine the optimal colorspace based on oneor more colorspace conversion operations, where the colorspaceconversion operations can provide a mechanism for encoding informationin any suitable medium, including but not limited to a matrix, such as amatrix barcode, a fiducial marker, any other suitable barcode, or anyother suitable image. The logic 160 can be further operative to causethe processing circuit 140 to generate a scheme for a matrix, e.g., amatrix barcode, fiducial marker, etc. based on the colorspacedetermination and for detection in relation to the particular object,entity, or environment. The logic 160 can further be operative to causethe processing circuit 140 to provide for a scheme to add at least oneultraviolet layer and infrared layer to an image, such as a matrix ormatrix barcode, useful for detection in relation to the particularobject, entity, or environment, where the ultraviolet layer and/orinfrared layer add additional data carrying capacity and/or security tothe detectable image.

The one or more colorspace models as described herein, as stated andimplied elsewhere herein, refers to any suitable colorspace model, suchas colorspace employing a tristimulus system or scheme, theRed-Green-Blue (RGB), the Luminance-Alpha-Beta (LAB), an XYZ colorspace,and/or the like and/or variations of the same. Similarly, althoughvarious embodiments may refer to a particular conversion from onespecific colorspace to another specific colorspace, conversions betweenother color spaces are contemplated and consistent with the teachings ofthe present disclosure.

In various embodiments, as described herein, one colorspace model (e.g.,RGB or XYZ) may correspond to a higher likelihood of success in edgedetection than another colorspace model in terms of detection of adisplayed or printed image, e.g. barcode, in relation to an object,entity, or environment with a particular color distribution. Moreover,particular colors and color-channels associated with a colorspace mayoffer superior edge detection in relation to the object, entity, orenvironment. Some images provide optimal or near-optimal edge detectionresults when arranged in RGB while other images provide optimal ornear-optimal edge detection results when arranged in XYZ or LAB and viceversa. By way of example, an image depicting a red balloon on a greenfield would appear much different in RGB than in LAB; therefore, withrespect to edge detection, LAB would provide a higher likelihood thanRGB at successfully identifying and locating edges (e.g., boundaries) ofthe red balloon, or a matrix, e.g., barcode or fiducial marker, that hada red color in the green environment.

In various embodiments, a color-channel is a distribution of colors witha first color and second color of first and second highest prevalence,respectively, where the first color becomes a minimum in the colorchannel and the second color becomes the maximum such that the boundarymay be a transition between these colors. This boundary may be at leastone pixel where the color changed from the first to the second color orvice versa. If the first color is set to zero (0) and the second coloris set to two hundred and fifty-five (255), then, mathematically, thisboundary may be located at pixel(s) that jumped between the minimum andmaximum value; for example, there may be sharp division (i.e., thinboundary) in which at least two neighboring pixels transitionimmediately between 0 and 255. In various embodiments, color-channels,e.g., “R,” “G,” and “B” define a colorspace such as RGB (e.g., a firstcolorspace based on a tristimulus system), and in various embodimentscustom color-channels can be created using a (second) tristimulus systemassociated with and defining an XYZ colorspace (and/or conversions to anXYZ colorspace). In various embodiments, the color-channels can begreater than three.

In various embodiments, as discussed herein, one or more color-channelranges are selected such that a maximum color value of one or more colorchannel corresponds to a unique color value, most prevalent color value,and/or highest color value of a target object, entity, and/orenvironment associated with a scan and the minimum color value of thecolor-channel corresponds to a most unique color, most prevalent colorvalue and/or highest color value of the scannable image, e.g. matrix,matrix barcode, and/or fiducial marker, where additionally, the mostprevalent value and/or highest color value of the scannable image isalso a least prevalent (lowest color value) and/or absent from thetarget object, entity, and/or environment associated with the scan, orvisa-versa (e.g. with respect to the maximum or minimum values).

In various embodiments, as described herein, particular objects,entities, or environments may have color distributions that make morecomplicated and varied colorspaces, and colors and color-channelsassociated therewith, including colors imperceptible by the human eye,more attractive for detection, in addition to increasing capacity forstorage and encryption of information. As such, in various embodiments,the logic 160 is further operative to cause the processing circuit 140to identify an image group corresponding to the patched image data. Theimage datasets 170 further includes image group model data correlatingimages with a colorspace transform model most likely to provideappropriate edge detection results. In some embodiments, the image groupmodel data indicates which colorspace transform model to use intransforming a given image prior to edge detection in order to achievenear-optimal edge detection results. The logic 160 is further configuredto cause the processing circuit 140 to select a colorspace transformmechanism 180 based upon the image group. The colorspace transformmechanism 180 is operative to transform the image data into transformedimage data in accordance with another colorspace model, the othercolorspace model having a higher likelihood than the colorspace model atedge detection for the image group.

In various embodiments, the system 100 can include one or more of acamera or video device 195 and/or a scanning device 197, where bothdevice 195 and device 197 can be any suitable device for obtaining,capturing, editing, and/or scanning images, including but not limited tovideo or camera pictures, of objects, entities, and/or environments. Thelogic 160 can be configured to capture or scan images of a particularobject, entity or environment using device 195 and/or device 197, wherethe captured images can become part of image datasets 170 and used fordetermining suitable colorspaces, performing colorspace conversions,and/or scanning images determined from colorspace conversions, as may beconsistent with the teachings provided herein.

In various embodiments, the system 100 can include a printing device 199(e.g. printer) or an application for the same, where images part ofimage datasets 170 and/or images generated by one or more components ofsystem 100, by applying a colorspace transformation technique ormechanism, such as a scannable matrix, matrix barcode, or fiducialmarker can be printed by printing device 199 and/or printing device 199can provide a scheme for another device to print or generate an image inassociation with the scannable matrix, matrix barcode, or fiducialmarker.

FIG. 2A illustrates an embodiment of a clustering process 200A for thesystem 100. The clustering process 200A operates on image datasets(e.g., the image datasets 170 of FIG. 1 ) storing color data for images.

In some embodiments of the clustering process 200A, color data 202 of animage undergoes a patching operation where the image is processed into aplurality of patches 204 of patched image data 206. Each patch 204 ofthe patched image data 206 includes color data in accordance with acolorspace model, such as pixel data having RGB tuples. The clusteringprocess 200A further processes the patched image data 206, via atransformation operation 208, by applying a colorspace transformmechanism on the color data of the patched image 206 to transformpatched image data into transformed image data of a transformed image210. The color data of the patched image 206 is configured in accordancewith the colorspace model and new color data for the transformed image210 is generated according to another colorspace model.

In some embodiments, the clustering process 200A performs amini-colorspace transform for at least one patch of the patched image206, possibly leaving one or more patches without a transformation. Viathe transformation operation 208, the mini-colorspace transform modifiesthe color data in the at least one patch to transform patched image datainto transformed image data of a transformed image 210. The clusteringprocess 200A may perform stitching between patches to make the patchedimage 206 uniform as opposed to creating artificial edges.

FIG. 2B illustrates an example of a colorspace conversion scheme 200B inaccordance with various embodiments of the present disclosure. Ahistogram 218 representation of a particular object, entity, orenvironment 215 is provided (where the numbers 100, 90, 80, and 70 areintended to represent a simplified version of colors distribution valuesof one or more colors representing the particular object, entity, orenvironment 215). The histogram 218 can be generated by having one ormore components of system 100 performing a scan of the particularobject, entity, or environment 215 and generating a histogram 218 of themost prevalent colors, least prevalent colors, or absent colors of theobject, entity, or environment 215. In one or more embodiments, thehistogram 218 can be of four or more colors of the most prevalent colorsof the object, entity, or environment. Since various embodiments of thepresent disclosure expressly contemplate using colors imperceptible tothe human eye, there is no limitation on the number of colors that canbe used with respect to the histogram 218, the colorspace conversionsdiscussed herein, or any images generated from the colorspaceconversions, including but not limited to a matrix, matrix barcode,fiducial marker, etc. can have in excess of four colors and fourcolor-channels, where the four colors and/or four color-channels aredistinct and different with respect to one another.

In various embodiments, one or more components of system 100 candetermine the most prevalent colors associated with the object, entity,or environment 215, and the resulting histogram 218 may be based on thatdetermination. The histogram 218 can be used to map the most prevalentcolors to a distribution 222 associated with a suitable colorspace 224,including but not limited to an RGB colorspace 224. In variousembodiments, the colors of histogram 218 are mapped pursuant to thetristimulus values of the RGB colorspace, e.g., “R,” “G,” and “B.” Anysuitable mathematical conversion, e.g., linear-algebraic, etc. can beused to map the conversion to the RGB colorspace, e.g., convert themapped RGB colorspace to another colorspace.

In various embodiments, once the distribution 222 is mapped according tothe RGB colorspace 224, one or more components of system 100 can convertthe RGB distribution 222 to a new colorspace 226 with a distribution 228pursuant to the new colorspace 226. Any suitable colorspace conversioncan be used, including converting to an XYZ colorspace, where theconversion can be pursuant to any suitable mathematical conversions andequations that govern the XYZ colorspace, including suitable tristimulusconversions between RGB and XYZ. In various embodiments, “Y” representsa luminance value of the XYZ space and at least one of “X” and “Z” (orboth) represent a chrominance value of the colorspace and an associateddistribution, e.g. 226 plotted pursuant to the XYZ colorspace.

In various embodiments, the luminance channel “Y” is filtered outresulting in colorspace 228′ and distribution 226′, which can assist inmaking determinations solely on actual chromatic values associated withthe entity, object, or environment 215, without considering luminance(this is helpful at least because colors can be used that areimperceptible to the human eye). In various embodiments, four (or more)lines can be defined by points (a1, b1), (a2, b2), (a3, b3), and (a4,b4), and are selected to have a maximum distance apart with respect todistribution 226′. In various embodiments, the points a1, a2, a3, and a4are selected to correspond to the most prevalent colors associated withentity, object, or environment 215 and b1, b2, b3, and b4 by extension,being opposite to those colors, may represent the least prevalent orabsent colors in association with an entity, object, or environment b1,b2, b3, b4. These lines may define vectors for a new colorspaceconversion in an XYZ or other suitable colorspace 245 and may form thebasis for new XYZ tristimulus values. An image, such as a matrix ormatrix barcode, can be made using colors associated with the newcolorspace 250 and a distribution 245 of colors defined by color-channelvectors (i, −i), (j, −j), (k, −k), an additional color-channel and allother color-channels (omitted from display due to the limitations ofthree-dimensional space) associated therewith. In various embodiments,since the colors may correspond to less prevalent or absent colors inrelation to where a potential scan may occur (or what is being scanned),e.g., a matrix barcode on an entity or object and/or in an environmentwith colors that have a maximum difference in relation thereto, edgedetection is enhanced.

Alternatively, although not expressly shown, the maximum distance fromthe most prevalent colors to least prevalent colors can be determined,e.g., a1 to b1, a2 to b2, etc., and then lines can be drawn from b1, b2,b3, and b4 in a direction tangential, parallel or opposite a vector ordirection associated with a1, a2, a3, and a4. The color-channel vectors(i, −i), (j, −j), (k, −k), an additional color-channel and all othercolor-channels (omitted from display due to the limitations ofthree-dimensional space) associated with colorspace 250 may be entirelycolors absent and/or mildly prevalent in relation to entity, object, orenvironment 215, which can further enhance edge detection.

In various embodiments, when performing the colorspace conversionbetween 228′ and 250, in addition to carrying out the algebraic or othersuitable conversions associated with the XYZ colorspace, thecolor-channel vectors, e.g. (i, −i), (j, −j), (k, −k), may be orthogonalto one another by performing any suitable mathematical and/ororientation operation on the vectors and/or by selecting suitable pointson colorspace 226′ and distribution 228′ when making the conversion. Invarious embodiments, a second maximum difference between one or morepoints can be taken in space 250, in addition to an orientationoperation to center the distribution 245 along the axis of the newlydefined color-channel vectors, e.g. (i, −i), (j, −j), (k, −k), such thatthe color-channel vectors are orthogonal and have a maximum distance inrelation to one another. In various embodiments, performing at least oneof the orthogonality operation, maximum determination, and/or orientingoperation can further enhance edge detection of an image generated forscanning, such as a matrix barcode, in relation to an entity, object, orenvironment 215 to be scanned.

In various embodiments, the various color-channels described above,including each vector, e.g. (−i, i), defines a first color that is aminimum in the color channel and the second color becomes the maximum.This boundary may be at least one pixel where the color changed from thefirst to the second color or vice versa. If the first color is set tozero (0) and the second color is set to two hundred and fifty-five(255), then, mathematically, this boundary may be located at pixel(s)that jumped between the minimum and maximum value; for example, theremay be sharp division (i.e., thin boundary) in which at least twoneighboring pixels transition immediately between 0 and 255. In variousembodiments, the boundary is such it may be a transition between thesecolors where, as discussed above, one or more color-channel ranges areselected such that a maximum color value of one or more color channelcorresponds to a unique color value, most prevalent color value, and/orhighest color value of a target object, entity, and/or environmentassociated with a scan and the minimum color value of the color-channelcorresponds to a most unique color, most prevalent color value and/orhighest color value of the scannable image, e.g. matrix, matrix barcode,and/or fiducial marker, where additionally, the most prevalent valueand/or highest color value of the scannable image is also a leastprevalent (lowest color value) and/or absent from the target object,entity, and/or environment associated with the scan, or visa-versa (e.g.with respect to the maximum or minimum values).

The length of the color-channel can be adjusted accordingly based on thecapabilities of the scanning and image-acquiring abilities of thevarious components, e.g. camera or video device 195, scanning device197, and/or recognition component 422-4 (discussed below with respect toFIG. 4 ), where the length increases the number of different colorsbetween the minimum and maximum point of the color channel.

In various embodiments, the conversions between the RGB colorspace tothe XYZ colorspace and/or a first converted-to (derivative)XYZ space toanother XYZ colorspace can be governed by the tristimulus equations(Equation 1) that define the converted colorspace and a distribution ofcolorspace, where the value of x+y=z can be normalized to 1.

x=X/(X+Y+Z),

y=Y/(X+Y+Z),

z=Z/(X+Y+Z).   Equation 1

In various embodiments, the value of “X,” “Y,” and “Z,” is dependent onthe input colors from the RGB colorspace (or in the case of a secondconversion, from the converting colorspace). Although the tristimulusvalues are three be definition, as noted above, the conversion caninvolve more than three color-channels, including color-channels thatdefine colors imperceptible to the human eye. In various embodiments,the conversion governed by Equation. 1 can form a key for a scanningdevice to scan an image defined by the conversion, such as a matrix,e.g., matrix barcode or fiducial marker. In various embodiments, thismeans that in addition to providing a vehicle for increasing the numbersof color-channels and colors for an image to be scanned, which meansincreasing bits of information that can be encoded therein, anotherbenefit of various embodiments is offering a manner to securely encodeinformation, e.g. without knowing the equation or equations of whatcolorspace govern and without knowing the input values (which are basedon the first colorspace associated with the entity, object, orenvironment 215), a successful scan cannot occur. Accordingly, invarious embodiments, the logic 160 of system 100 can cause a processor140 (or an application programmed to carried out the operations of 100)to provide a scanning device 197 with a key governed by Equation 1 inorder to scan an image that is encoded pursuant to one or morecolorspace conversions associated with Equation 1.

In various embodiments, the logic 160 of system 100 can cause aprocessor 140 to provide a scheme for adding either one or both of anultraviolet layer and/or an infrared layer to an image, such as amatrix, e.g. matrix barcode or fiducial marker, where the image containsmore than one non-black or non-white colors governed by any suitablecolorspace. In various embodiments, the scheme may include both anultraviolet layer and an infrared layer, where the ultraviolet layer mayform the first layer of an image in order to take advantage of itsproperties. In various embodiments, the non-black and non-white colorsof the scannable image may be determined by one or more colorspaceconversion techniques as outlined herein. In various embodiments,Non-black and non-white colors means colors that are not black or white.In various embodiments, non-black and non-white colors means colors thatare not black, white or based on a greyscale distribution.

FIG. 4 illustrates an embodiment of an operational environment 400 forthe system 100. As shown in FIG. 4 , the operating environment 400includes an application 420, such as an enterprise software application,for processing input 410 and generating output 430.

The application 420 comprises one or more components 422-a where arepresents any integer number. In one embodiment, the application 420may comprise an interface component 422-1, a clustering component 422-2,a transform mechanism library 422-3, and a recognition component 422-4.The interface component 422-1 may be generally arranged to manage a userinterface for the application 420, for example, by generating graphicaldata for presentation as a Graphical User Interface (GUI). The interfacecomponent 422-1 may generate the GUI to depict various elements, such asdialog boxes, HTML forms having rich text, and/or the like.

The clustering component 422-2 may be generally arranged to organizeimages into image groups or clusters. Some embodiments of the clusteringcomponent 422-2 execute the clustering process 200A of FIG. 2A and/orone or more of the colorspace conversion operations of scheme 200B ofFIG. 2B and generates the image group model data 350 of FIG. 3 . Invarious embodiments, the clustering component 422-2 identifies, for eachimage group, a particular colorspace transform having a higherlikelihood than a current colorspace transform of success in edgedetection for that group as outlined herein or otherwise suitable. Invarious embodiments, the clustering component 422-2 may perform theabove-mentioned clustering process for a variety of edge detectiontechniques, resulting in sets of image groups where each set of imagegroups corresponds to a particular technique. Edge detection techniquesvary in how boundaries are identified in an image; some techniquesdetect differences in color whereas other techniques measure anotherattribute. Some techniques differ with respect to how color differencesare even measured. It is possible for one technique to alter certainsteps and create multiple techniques.

The colorspace transform library 422-3 includes a plurality ofcolorspace transform mechanisms and may be generally arranged to providea colorspace transform mechanism for application on an image,transforming that image into a transformed image in accordance with adifferent colorspace model than the image's original colorspace model.As described herein, the colorspace model refers to a technique formodeling an image's color data, such as in RGB or in LAB, or RGB to XYZ,or RGB to XYZ to another XYZ. In general, and as outlined in one or moreembodiments herein, the colorspace transform mechanism performsmathematical operations to map a data point within the image'soriginal/current colorspace model into a corresponding datapoint inaccordance with the different colorspace model. This may involveconverting the datapoint's value(s)—which are in one domain—intocorresponding value(s) for the corresponding datapoint. As example, thecolorspace transform may convert an RGB pixel having a tuple of RGBvalues into a LAB pixel having a tuple of LAB values, an RGB pixelhaving a tuple of RGB values into an XYZ pixel having a tuple of XYZvalues, and/or an RGB pixel having a tuple of RGB values into an XYZpixel having a tuple of XYZ values and again into another XYZ pixelhaving a tuple of other XYZ values. The pixels associated with the finalconversion can define a color distribution for a scannable image, suchas a matrix or matrix barcode that is used for a scan in associationwith an entity, object, or environment.

The recognition component 422-4, such as a suitable scanner, printerand/or camera or application for the same, may be generally arranged toexecute an edge detection technique as part of a recognition operationon the transformed image. One example of a well-known recognitionoperation is Optical Character Recognition (OCR). The application 420invokes the recognition component 422-4 to perform various tasksincluding scanning a matrix, e.g., matrix barcode or fiducial marker,for verifying an authenticity of an item and/or to obtain encodedinformation associated with the barcode. The recognition component 422-4can be configured to contain a key, e.g. a mathematical equation orequations with specified inputs defining a colorspace conversion, suchthat it scans relevant colors reflected by the barcode, where the colorsare based on one or more colorspace transformation techniques asoutlined herein, where the key defines a final transformation thatdefines color-channels and a colorspace associated with colors of thescannable image, and where color-channels defined by the key eachrepresent at least one bit of encoded data.

In various embodiments, the recognition component 422-4 can print orprovide a schema for printing an image, e.g., barcode and/or fiducialmarker, that contains one or more non-black and non-white colors and oneor both of an ultraviolet layer and an infrared layer. Thecolor-channels associated with each non-black and non-white color eachcan constitute at least one bit of data, and each one of the infraredand ultraviolet layers can each constitute one bit of data. In variousembodiments, each one of the non-black and non-white colors aregenerated by a colorspace transformation mechanism or technique and arescannable by a key associated with the transformation mechanism. Invarious embodiments, the number of color-channels can be adjusted to begreater than or equal to four color-channels, as the recognitioncomponent 422-4 can be adjusted to scan any number of colors, includingcolors not perceptible to the human eye.

In various embodiments, the non-black and non-white color-channel can beused in conjunction with one or both of the infrared or ultravioletlayers on a scannable image, such as a matrix, matrix barcode and/orfiducial marker, where each of one of the color-channels, ultravioletlayer(s), and/or infrared layer(s) represent a bit of data and adifferent manner of encoding data into the image, and as such, six ormore bits of data can be encoded into the image. In various embodiments,the ultraviolet layer may be printed or displayed first in relation tothe infrared layers and the various layers associated with non-black andnon-white color-channels to take advantage of the ultraviolet layer'sproperties.

In various embodiments, the image containing all or one of the layersassociated with the non-black and non-white color-channel layers, theultraviolet layers, and the infrared layers can be scanned by therecognition component 422-4 for a verification component, where therecognition component 422-4 may contain or receive a key that is basedon an equation related to a colorspace conversion, e.g. Equation 1,where the colorspace conversion reveals the relevant color-channels withassociated colors containing the information, in addition to one or moreverification bits indicating whether the presence or absence of anultraviolet and/or infrared layer is indicative of encoded information.Accordingly, the key and/or verification bit provides a manner ofdecoding information.

In various embodiments, application 420 is configured to contain the keyand/or verification bit and provide an output 430 once the scan of theimage, e.g., barcode, is verified locally. In various embodiments, therecognition component 422-4 can require an additional verification stepof contacting a host system that contains one or more of thefunctionalities of system 100, to confirm, e.g., by one or morecomparison steps, that the key and/or verification bit used by therecognition component 422-4 is accurate. If the key is accurate, and thescan is confirmed by the recognition component 422-4, then the output430 of application 420 is one or more access, transfer, or receipt ofinformation, including currency, personal, and/or financial information,to another entity.

In various embodiments, scanning the image, e.g., matrix, a matrixbarcode, and/or fiducial marker can be done to protect a user fromfinancial misappropriation. The recognition component 422-4 may performthe text or image recognition operation to determine whether the image,e.g., barcode, is valid, and relates the validity of the scan to averification or access of information that includes any sensitiveinformation, such as a password or social security number (SSN),according to some embodiments. The application 420 may invoke therecognition component 422-4 to scan an image, e.g. a barcode, prior topublishing social network content such that a potential failure toproperly scan the image, e.g. the component scanning the image does nothave a key that properly decodes it pursuant to the key related to thecolorspace information and/or the bit indicating that an ultravioletand/or infrared layer contains information, identification of sensitiveinformation in that content prevents said publishing. In various otherembodiments, the scanning of the image, e.g., barcode, can provideinitiation of a financial transaction, e.g., transfer of any suitableelectronic funds.

FIG. 5A illustrates one embodiment of a logic flow 500A. The logic flow500A may be representative of some or all of the operations executed byone or more embodiments described herein.

In the illustrated embodiment shown in FIG. 5A, the logic flow 500Areceives a representative dataset of a target, such as an entity,object, or environment 502. For example, the logic flow 500 may receivea representative dataset containing at least one of i) one or moreimages of a target and ii) one or more videos of the target, the targetincluding at least one of i) an environment, ii) a live entity and iii)an object using any suitable camera or scanning device, where therepresentative dataset is contained in image group model data 350 orobtained directly by scanning the target using any suitable device,e.g., camera or video device 195 and/or scanning device 197. In variousembodiments, the target may be an environment that contains a scannableimage therein.

The logic flow 500A may process the representative dataset into asuitable representation of a color scheme, such as a histogram 504. Forexample, the logic flow 500 may examine image group model data 350,which contains captured data of a scanned environment. Once the logicflow 500 identifies the scanned data of the environment, the logic flowcan process that data into a histogram of a particular colorspace, e.g.,an RGB colorspace.

The logic flow 500A may identify the most prevalent colors of theenvironment utilizing the histogram 506. In various embodiments, thelogic flow identifies the most prevalent colors in order to apply acolorspace transform mechanism for substantially maximizing edgedetection for a scannable image, such as a matrix, matrix barcode,fiducial marker, etc.

The logic flow 500A may determine a related number of colors based onthe histogram 508, e.g., the histogram is used to map to a firstcolorspace, where least prevalent and/or absent colors in relation tothe most prevalent colors of the target are determined, and the leastprevalent and/or absent colors form the basis for one or morecolor-channels in a second colorspace.

In various embodiments, the related plurality of colors can represent arange of colors between the most prevalent colors and the leastprevalent colors and/or absent colors of the target, including solecolors that are absent in relation to the target and/or colors that arethe least prevalent in association with the target. In variousembodiments, in order to determine the related number of colors based,the logic flow may select and apply a colorspace transform mechanism tothe image data associated with the histogram. As described herein, theimage data includes color data configured in accordance with acolorspace model, e.g., the histogram can be used to create a colorspacerepresentation of the target data. In some embodiments, the logic flow500 applies the colorspace transform mechanism 180 of FIG. 1 byconverting the image data into transformed image data comprising colordata in accordance with another colorspace model that differs from thecolorspace associated with the histogram. For example, the logic flowmay create a histogram of the image data associated with the target,then use the histogram to create a first colorspace representation ofthe target, e.g., an RGB colorspace representation. Thereafter, asdiscussed below, the logic flow can perform one or more additionalcolorspace transformation techniques into other colorspaces, such as XYZcolorspaces or any other suitable colorspace that utilizes a tristimulussystem.

In various embodiments, the logic flow 500A may perform a colorspacetransform manipulating the color data of the original image data toenable efficient edge detection on the transformed image data. Asexplained below, the logic flow 500A may change the colorspace model toquickly identify boundaries, such as when two colors are close inproximity. The logic flow 500A examines each datapoint in the image, andfor each location, the logic flow 500A identifies a color. In variousembodiments, the colorspace conversion can be based on at least one setof color coordinates for each one of the most prevalent colors accordingto the another (or second) colorspace and determining at least one setof color coordinates corresponding to the related plurality of colors inthe (second) another colorspace, where the at least one set ofcoordinates of the most prevalent plurality of colors being either oneor both of perpendicular/orthogonal and a maximal distance away, withrespect to another colorspace, to the at least one set of coordinates ofthe related colors. In various embodiments, the second colorspace can beconsidered a derivative colorspace of the first color space.

In various embodiments, this ensures that the colors used for ascannable image may maximize edge detection, as the maximal distanceaway between prevalent color-channels and colors of the target in theenvironment and other color-channels and colors (the relatedcolor-channels and colors) ensures that the related color-channels andcolors are either absent in the target and/or least prevalent in thetarget. Additionally, if the related colors and color-channels areselected to be perpendicular or orthogonal in relation to the targetcolor-channels and colors (and with respect to one another), this mayfurther enhance edge detection.

In one example utilizing the one or more techniques outlined above, thelogic flow 500A proceeds to identify two or more colors by prevalence inthe target and configures them into one channel. Take, for instance, afirst color and second color of first and second highest prevalence,respectively, where the first color becomes a minimum in the colorchannel and the second color becomes the maximum such that the boundarymay be a transition between these colors. This boundary may be at leastone pixel where the color changed from the first to the second color orvice versa. If the first color is set to zero (0) and the second coloris set to two hundred and fifty-five (255), then, mathematically, thisboundary may be located at pixel(s) that jumped between the minimum andmaximum value; for example, there may be sharp division (i.e., thinboundary) in which at least two neighboring pixels transitionimmediately between 0 and 255.

As alluded to above, these color-channels can correspond to a firstcolorspace, e.g., RGB, where the first colorspace can be based on thefirst set of tristimulus values, and where the first-colorspace may havea color coordinates for representing colors of the target, e.g., themost prevalent colors of the target. The logic flow 500A may thenidentify one or more colors that are either unused or barely used (i.e.,least prevalent or absent) and establish those colors in another channelto be opposite of the above-identified prevalent colors, where the newcolor-channel (or color-channels) forms the basis for a new colorspace,e.g., a new set of tristimulus values of an XYZ colorspace, and wherethe first colorspace is converted to the second colorspace.

Then, the logic flow 500A may perform one or more additional operations,e.g. configuring each color-channel of the new colorspace to beperpendicular or orthogonal to one another in the new colorspace model,make an additional conversion to a third colorspace, including anintermediary operation that filters out non-chromacity related featuressuch as luminance or brightness channel, and/or perform an orientationoperation in the second (or third) colorspace prior to making thecolor-channels perpendicular or orthogonal to each other (in order tomaximize the distance between color-channels and thus enhancing edgedetection).

The logic flow 500A may utilize the related colors of block 508 tocreate one or more scannable images 510, such as a matrix, matrixbarcode, fiducial marker, or any other suitable image for scanning. Invarious embodiments, the related colors may be colors of eachcolor-channel associated with the final colorspace conversion asdiscussed above, e.g. a plurality of color-channels and associatedcolors, as may be represented in an XYZ colorspace, that are either notprevalent in the target and/or are completely absent in the target,where, in various embodiments, the least prevalent and/or absent colorscan be arranged orthogonally to each other to further enhance edgedetection. In various embodiments, the scannable image may be a matrixbarcode that is formed to reflect colors of each of the least prevalentand/or absent and/or orthogonal color-channels in relation to a target,e.g., environment containing the matrix barcode.

In various embodiments, the matrix barcode is embedded with informationthat is based on the colorspace conversions, e.g., each pixel or pixelsassociated with the matrix bar code is associated with a color-channelof the final colorspace, e.g. the XYZ colorspace with color-channelsrepresenting the least prevalent or absent colors of the environment,where each color-channel represents a bit of data, and where the numberof color-channels can be three or more, four or more, etc. (as there areno limitations imposed by human perceptibility), and by extension thenumber of encoded bits can be three or more, four or more, etc.

In various embodiments, where four or more colors are used, each one ofthe four or more colors are distinct colors in relation to one another,and based on the colorspace techniques discussed herein and above, thefour or more colors are derived from a plurality of coordinatescorresponding to each one of the at least four distinct colors along aconverted-to (derivative) colorspace, where the converted-to(derivative) colorspace contains a plurality of coordinates setsrepresenting the at least four prevalent colors of the target, e.g.,environment, and each of the four or more colors corresponds to adistinct coordinate set of the converted-to (derivative) colorspace.

In various embodiments, the scannable image 635 b is a fiducial markerthat takes advantage of the inherent orienting features of ultravioletand/or infrared light when being scanned by a suitable device that candetect either one or both of ultraviolet and/or infrared light. Invarious embodiments, when a suitable device, e.g., scanning device 197,scans a fiducial marker 635 b that reflects ultraviolet and/or infraredlight, the spatial relationship of the object associated with thefiducial maker 635 b, e.g. an object with the fiducial marker labeledthereon and/or a computer display generating the fiducial marker 635 b,in relation to the scanning device 197 and other objects in anenvironment containing the device is easier to ascertain because of theinherent properties associated with the reflection and detection ofultraviolet and/or infrared light.

FIG. 6C illustrates one technique 600C of forming a scannable image inaccordance with at least one embodiments of the present disclosure.Scannable image layers 605 c, 610 c, 615 c, and 620 c each represent alayer of a scannable image, such as a barcode, associated with one ormore colors. Any suitable component as disclosed herein may perform oneor more colorspace transformation techniques on each scannable imagelayers 605 c, 610 c, 615 c, and 620 c in order to produce layers 625 c,630 c, 635 c and 640 c, and layers 625 c, 630 c, 635 c and 640 c may beconsolidated into a single scannable image, e.g., barcode, 645 c. Invarious embodiments, the scannable layers 625 c, 630 c, 635 c and 640 cmay each be associated with a color-channel that represents one or morecolors that are absent and/or not prevalent in relation to a target thatmay be associated with the scannable image 645 c, where in variousembodiments one or more color-channels associated with colors of 625 c,630 c, 635 c and 640 c may be orthogonal or perpendicular in relation toone another and with respect to colorspaces representing those colors.

In various embodiments, at least one layer, e.g. 635 c, can be made withinfrared ink or generated using infrared light such that it contains anadditional channel of information, e.g., an ultraviolet layer ofinformation, which can absorb, reflect, project, and/or illuminateinfrared light, where in various embodiments the infrared layer 630 cmay be the first layer of image 635 c. In various embodiments, theinfrared layer 630 c may contain a color-channel layer representingvarious colors, including colors that are not prevalent and/or absentfrom a target to be associated with the scannable image 645 c, and invarious embodiments, only an infrared channel may be associated with theinfrared layer 630 d. In various embodiments, at least one layer, e.g.640 c, can be made with ultraviolet ink or generated using ultravioletlight such that it contains an additional channel of information, e.g.,an ultraviolet layer of information, which can absorb, reflect, project,and/or illuminate ultraviolet light, where in various embodiments theultraviolet layer 640 c may be the first layer of image 645 c. Invarious embodiments, the ultraviolet layer 640 c may contain acolor-channel layer representing various colors, including colors thatare not prevalent and/or absent from a target to be associated with thescannable image 645 c, and in various embodiments, only an ultravioletchannel may be associated with the ultraviolet layer 640 c.

In various embodiments, the scannable image 645 c is a fiducial markerthat takes advantage of the inherent orienting features of ultravioletand/or infrared light when being scanned by a suitable device that candetect either one or both of ultraviolet and/or infrared light. Invarious embodiments, when a suitable device, e.g., scanning device 197,scans a fiducial marker 645 c that reflects both ultraviolet andinfrared light, the spatial relationship of the object associated withthe fiducial maker 645 c, e.g. an object with the fiducial markerlabeled thereon and/or a computer display generating the fiducial marker645 c, in relation to the scanning device 197 and other objects in anenvironment containing the device is easier to ascertain or detectbecause of the inherent properties associated with the reflection anddetection of ultraviolet and/or infrared light. In various embodiments,where fiducial marker 645 c utilizes both ultraviolet and infraredlight, the presence of both operates as a fail-safe if the functionalityof the scanning device 197 is compromised, and/or if an initial scanfails to detect one or the other.

Although at least oneembodiment provided above indicates that either one or both of layers635 c and 640 c can include color-channel information, e.g., scannablecolors that have a relationship with a target, in various embodiments,layers 635 c and 640 c can be associated strictly with infrared and/orultraviolet information respectively. Moreover, in various embodiments,the colors of layer 620 c, 625 c, and 630 c do not have to be layer thathas a relationship with the target, and in various embodiments, saidlayers can be composed of black and white colors and/or other colorsunrelated to the target and/or not based on colorspace conversiontechniques.

The clients 1002 and the servers 1004 are operativelyconnected to one or more respective client data stores 1008 and serverdata stores 1010 that can be employed to store information local to therespective clients 1002 and servers 1004, such as cookies and/orassociated contextual information.

The clients 1002 and the servers 1004 may communicate informationbetween each other using a communication framework 1006. Thecommunications framework 1006 may implement any well-knowncommunications techniques and protocols. The communications framework1006 may be implemented as a packet-switched network (e.g., publicnetworks such as the Internet, private networks such as an enterpriseintranet, and so forth), a circuit-switched network (e.g., the publicswitched telephone network), or a combination of a packet-switchednetwork and a circuit-switched network (with suitable gateways andtranslators).

The communications framework 1006 may implement various networkinterfaces arranged to accept, communicate, and connect to acommunications network. A network interface may be regarded as aspecialized form of an input output interface. Network interfaces mayemploy connection protocols including without limitation direct connect,Ethernet (e.g., thick, thin, twisted pair 10/100/1000 Base T, and thelike), token ring, wireless network interfaces, cellular networkinterfaces, IEEE 802.11a-x network interfaces, IEEE 802.16 networkinterfaces, IEEE 802.20 network interfaces, and the like. Further,multiple network interfaces may be used to engage with variouscommunications network types. For example, multiple network interfacesmay be employed to allow for the communication over broadcast,multicast, and unicast networks. Should processing requirements dictatea greater amount speed and capacity, distributed network controllerarchitectures may similarly be employed to pool, load balance, andotherwise increase the communicative bandwidth required by clients 1002and the servers 1004. A communications network may be any one and thecombination of wired and/or wireless networks including withoutlimitation a direct interconnection, a secured custom connection, aprivate network (e.g., an enterprise intranet), a public network (e.g.,the Internet), a Personal Area Network (PAN), a Local Area Network(LAN), a Metropolitan Area Network (MAN), an Operating Missions as Nodeson the Internet (OMNI), a Wide Area Network (WAN), a wireless network, acellular network, and other communications networks.

Some embodiments may be described using the expression “one embodiment”or “an embodiment” along with their derivatives. These terms mean that aparticular feature, structure, or characteristic described in connectionwith the embodiment is included in at least one embodiment. Theappearances of the phrase “in one embodiment” in various places in thespecification are not necessarily all referring to the same embodiment.Further, some embodiments may be described using the expression“coupled” and “connected” along with their derivatives. These terms arenot necessarily intended as synonyms for each other. For example, someembodiments may be described using the terms “connected” and/or“coupled” to indicate that two or more elements are in direct physicalor electrical contact with each other. The term “coupled,” however, mayalso mean that two or more elements are not in direct contact with eachother, but yet still co-operate or interact with each other.
